Yun, who managed the Garden Health Spa as well as worked as a masseuse, allegedly had an encounter with a police informant April 2 where she openly discussed pricing for sexual favors, according to police.

When the informant told Yun he needed to go to the pharmacy to get his prescription for Viagra filled because he had diabetes, Yun allegedly said, "You should have been prepared."

The investigation was aided by Allegheny Township police, who in January and April, received information from men who were stopped in their vehicles after leaving Garden Health Spa.

A motorist from Elkhart, Ind., told police Jan. 28 that he paid $60 for a massage and afterward the masseuse, an Asian woman, got undressed and offered him "a date" for $140. The man allegedly told police he didn't have any money and was not interested.

Police stopped another motorist April 8 and were told by the man that he had just visited the spa and paid $60 for a one-hour massage. The man said the masseuse performed a sex act on him with her hand.

Lee is charged with prostitution, but no further details of her case were available Friday. A search of the Garden Health Spa turned up a large box of condoms, according to state police.

Thursday's arrests are not the first time state police have arrested a masseuse at the spa. In 2001, two undercover state troopers arrested a masseuse at the business and were criticized for allowing the woman to perform oral sex after paying her with police funds as part of the investigation. At the time, there was no policy regarding the issue, but subsequent policy changes now forbid it.

In that case, the masseuse pleaded guilty and was fined $458 while the massage parlor's owner, Routley, forfeited around $1,000.

Both women arrested Thursday remain free on unsecured bail, with bail set for Sun at $10,000 and Lee at $5,000.
